Press Releases

HOUSTON, May 15, 2018 (GLOBE NEWSWIRE) -- Moleculin Biotech, Inc., (NASDAQ:MBRX) ("Moleculin" or the "Company"), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced its financial results for the first quarter ended March 31, 2018. Additionally, the Company announced potential upcoming milestones and recent corporate developments.

Management Discussion

Walter Klemp, Chairman and CEO of Moleculin, said, “The first quarter of 2018 was very productive as we took important steps to advance the clinical trial of our lead compound, Annamycin for the treatment of relapsed or refractory acute amyloid leukemia (“AML”). We entered into an agreement with The University Hospitals Cleveland Medical Center, which includes the Seidman Cancer Center and the Cleveland Clinic, to participate in our U.S. Phase I/II clinical trial of Annamycin to demonstrate safety and efficacy. The first patients were enrolled and treated without incident beginning in late March 2018. We are also awaiting authorization to proceed with our Annamycin clinical trial in Poland, which, if approved by the Polish National Office, would provide a significant and positive expansion of our trial.”

“We are particularly excited with the commencement of the U.S. Annamycin clinical trial because of its unique attributes in treating cancer,” continued Mr. Klemp. “Currently approved drugs for AML are limited in their effectiveness by two key flaws: they are often defeated by something called multidrug resistance, which allows cancer cells to build a resistance to the drug, and at the same time, their dosage is limited by their inherent cardiotoxicity, meaning they can do significant and permanent damage to the heart. Annamycin was uniquely designed to avoid these multiple drug resistance mechanisms and exhibits little to no cardiotoxicity. We believe these unique characteristics could make Annamycin an important new treatment option for AML patients."

“Also, during the quarter, we engaged a contract research organization in anticipation of the expansion of the Annamycin clinical trial in Europe; and we entered into an agreement with a European-based manufacturer to begin preparations for commercial scale production of Annamycin as it moves through the approval process.

We remain highly focused on developing treatments for rare and difficult cancers such as AML; glioblastoma; cutaneous T-cell lymphoma, (“CTCL), a deadly form of skin cancer; and pancreatic cancer. We have three highly differentiated technologies with breakthrough potential that, we believe, may effectively treat these difficult cancers. From those three core technologies, we now have six potential oncology drug candidates - one of those drugs is currently in clinical trials - with the possibility of two others commencing clinical trial in 2018. We are off to a good start in the first quarter of 2018 and we look forward to building on that momentum throughout the rest of the year.”

Moleculin Announces Patients Treated in FDA Approved Phase I/II Annamycin Clinical Trial - April 04, 2018, the Company announced that patients have successfully begun treatment in its U.S. Phase I/II clinical trial of Annamycin for the treatment of relapsed or refractory AML. The first patient enrolled in Moleculin's Annamycin clinical trial was treated at The University Hospitals Cleveland Medical Center Seidman Cancer Center on March 28, 2018.

Moleculin Enters Agreement with Seidman Cancer Center to Conduct Leukemia Clinical Trials Patient -March 27, 2018, the Company announced that it has entered an agreement with The University Hospitals Cleveland Medical Center, which includes the Seidman Cancer Center and the Cleveland Clinic, to participate in its U.S. Phase I/II clinical trial of Annamycin for the treatment of relapsed or refractory AML. Patient enrollment has begun in the Phase I/II trial to demonstrate the safety and effectiveness of Annamycin in the treatment of AML in a U.S. clinical trial.

Moleculin Announces Grant-Funded Collaboration to Expand Understanding of New Discovery - March 20, 2018, the Company announced it has entered into a collaboration with a team of scientists in Poland who have received a $300,000 research grant to expand the understanding of how Moleculin's leading STAT3 inhibitor WP1066 and the Company's newly discovered drug candidate, WP1732, create a blockade of transcription factor STAT3 leading to tumor cell death and immune-stimulating effects.

Moleculin Announces Pricing of $9 Million Registered Direct Offering - February 16, 2018, the Company announced that it has entered into a definitive agreement with institutional investors for a registered direct offering of securities with gross proceeds of approximately $9 million.

Moleculin Announces Breakthrough Discovery of a New Molecule for Cancer Treatment - February 15, 2018, the Company announced that, pursuant to its continued collaboration with MD Anderson it has developed and licensed what it believes, based on preclinical testing, is a major breakthrough in its effort to develop a new cancer treatment that selectively kills highly resistant tumors. Specifically, the Company has preclinical evidence to suggest it is capable of influencing a process known as 'ubiquitination' to block the activated form of STAT3, an important oncogenic transcription factor. The lead molecule resulting from this new discovery is called WP1732 and it not only appears to share the same key mechanistic properties with WP1066, it has markedly different organ distribution and its dramatically increased solubility makes it ideal for administration via standard IV injection. Importantly, preclinical testing has also shown that WP1732's properties make it a promising candidate for treating pancreatic cancer.

Moleculin Announces Collaboration with Emory University to Develop Novel Treatment of Pediatric Brain Cancer - February 13, 2018, the Company announced it has entered into an agreement with Emory University to enable expanded cancer research on Moleculin's WP1066 molecule for the possible treatment of medulloblastoma, a pediatric malignant primary brain tumor. Physician-scientists at Emory University and Children's Healthcare of Atlanta have requested support to continue research aimed at the development of a novel treatment of medulloblastoma using WP1066 and Moleculin has agreed to supply them with a pure form of WP1066 for preclinical testing for the potential future treatment of patients with the disease. Emory studies so far have indicated that medulloblastoma may be particularly vulnerable to the ability of WP1066 to block the activated form of STAT3, a key signaling protein believed to contribute to the growth and survival of many tumors, including medulloblastoma.

Moleculin Announces Activity with Pancreatic Cancer Drug - February 7, 2018, the Company announced it has been able to show promising tumor suppression activity with its inhibitor of glycolysis, WP1122. The Company’s glycolysis inhibitors have shown a remarkable affinity for concentrating in the pancreas and has solid data showing the ability of WP1122 to inhibit pancreatic tumor growth in mice.

Leading Leukemia Experts Join Moleculin's Science Advisory Board - January 17, 2018, the Companyannounced the expansion of its Science Advisory Board to include Drs. Jorge Cortes and Elihu Estey.

Jorge Cortes, M.D., is deputy chair and professor of medicine in the Department of Leukemia at MD Anderson Cancer Center where he directs the CML and AML Programs.

The increase of approximately $0.6 million was mainly attributable to the increase in headcount and associated payroll costs of $0.3 million; $0.1 million of stock-based compensation; and, approximately $0.2 million in other expenses. Such increases are due to the increased corporate activity as the Company enters clinical trials.

Net Loss. The net loss for the three months ended March 31, 2018 was $1.9 million which included non-cash income of $0.2 million related to stock-based compensation and other stock-based expenses.

Liquidity and Capital Resources

As of March 31, 2018, the Company had $13.1 million in cash and cash equivalents. On February 16, 2018, the Company entered into a Securities Purchase Agreement with certain institutional investors for the sale by us of 4,290,000 shares of our common stock, at a purchase price of $2.10 per share. Concurrently with the sale of the common shares, pursuant to the Purchase Agreement, we also sold warrants to purchase 2,145,000 shares of common stock. We sold the common shares and warrants for aggregate gross proceeds of approximately $9.0 million. Subject to certain beneficial ownership limitations, the warrants will be initially exercisable on the six-month anniversary of the issuance date at an exercise price equal to $2.80 per share of common stock, subject to adjustments as provided under the terms of the warrants. The warrants are exercisable for five years from the initial exercise date. The closing of the sales of these securities under the Purchase Agreement occurred on February 21, 2018. The net proceeds from the transactions was approximately $8.2 million after deducting certain fees due to the placement agent and transaction expenses. The net proceeds will be used for planned clinical trials, preclinical programs, for other research and development activities and for general corporate purposes.
